every day another thing is wrong with this damn car anyways about half the time now when i turn my steering wheel i hear a very loud and apparently grinding screech coming from beneath the steering column. thats the only way i can really describe it as a grinding screetch and you can almost feel it in the wheel column, any idea what this could be? a problem with the power steering or maybe my wheel alignment?? Also i do have a custom exhaust is it grinding against the drivers side headers??
